Why can't we use a Vec<Text> or something for lists?

[jrmiller82]

I'm getting all sorts of compiler puke when trying to use the List and SelectableList widgets. It's looking like the library requires me to use a fixed array to give to List or SelectableList. Why can't I use a vec? This makes it a PITA when dealing with dynamic UI lists.

List and SelectableList require an Iterator as illustrated here:

tui-rs/examples/demo.rs

Line 333 in 5cee2af

let events = app.events.iter().map(|&(evt, level)| {

. Have you tried to call iter() on your Vec ? What was your error ?

I had an iterator, but it was an iterator coming from Vec<String> instead of Vec<&str>. I think the functions need to eventually also accept a Vec<String>.iter() instead of only a Vec<&str>.iter(). But I figured out how to get it to work in the meantime.
